Abstract
Controlling an encryption/decryption device using descriptors may include formatting a first block of memory to contain a generic data template used to control the encryption/decryption device. The first memory block may be configured with actual data values corresponding to the generic data template. At least a portion of the configured actual data values may be acquired and used for controlling one or more operations of the encryption/decryption device. A second memory block may be configured in a manner compatible with the first memory block format. The second memory block may also be configured with actual data values corresponding to the generic data template of first block of memory. The second block of memory may be linked to the first memory block. The first and second block of memory may be a random access memory.
